Buhner’s Stitch- After the vulva is replaced umbilical tape or a braided string is put vertically around each side of the vulva and tied below.
Bootlace Pattern or horizontal mattress- in this a strong braided suture is put in a crossing pattern going into the tissue of the vulva.
A prolapse kit is specially designed to go into the vulva and tack the vulva and through the muscles of the pelvis and gluteal muscles.
The traditional Buhner Stitch is the strongest hold. However, since these cows are generally late gestation, this method can also cause severe or fatal tears if the stitch is not removed before the cow calves.
The horizontal mattress patterns should also be removed but since they generally are as deep it is less detrimental if it not cut although, many times it can also cause death of the calf if doesn't break or doesn't tear fast enough. Lastly are the prolapse kits, the advantage is cows can calve unassisted without having to remove suture. The prolapse kits have a much higher chance of complications of damaging tissues that the pin is put through. This method generally is a little more expensive due to cost of the kit and putting it in. Since plastic is easily broken in cases that are severe, swelling is excessive or cow is intensely straining prolapse kits are not recommended.
the ability to monitor cows closely and get up easily the decision will vary between situations. However if she is kept and calves without complication, the weaned calf is more valuable than selling her as a weigh cow.
Vaginal prolapses are reoccurring, so even if she is kept to raise the calf. She should not be bred again, as each year the prolapses will be more difficult to repair. Also, with if she has a genetic predisposition, her offspring should be considered as culls. This is a more difficult decisions as when it occurs in mature cows, producers have often kept heifers as replacement females. For some small farms, this may mean a large percent of herd are at risk. Although her sons won't have a vagina to prolapse, if he is used for breeding his daughters may have problems. When buying a herd bull, pedigree and EPDs are generally readily available but medical history of dam and sire are not. For each farm, solutions may be different. Talk with your local vet, and consider the cost of repair and risks of complications.

After the prolapse is replaced management decisions can become difficult. As the cow is usually close to calving, should she or should she not be sold? Labor increases as cow will have to be watched as to make sure she doesn't break the prolapse kit by straining or if she has a stitch it must be removed shortly before she calves. So depending on the size of your farm and the ability to monitor cows closely and get up easily the decision will vary between situations. However if she is kept and calves without complication, the weaned calf is more valuable than selling her as a weigh cow.
